Product details
Overview
IDT7014S12PFG from Renesas Electronics is a high-speed 4K × 9 true dual-port static RAM with independent left/right ports, 12 ns maximum access time (commercial grade), TTL-compatible 5 V ±10% operation, and 750 mW typical active power consumption. It enables simultaneous asynchronous reads from the same memory location and supports parity-enabled data communication systems.
For engineers reviewing the IDT7014S12PFG datasheet, IDT7014S12PFG pinout, IDT7014S12PFG application, or IDT7014S12PFG equivalent, this part serves as a low-latency, arbitration-free dual-access memory for real-time inter-processor communication, video frame buffering, and telecom packet buffering where deterministic timing and port independence are critical.
Technical Context
The IDT7014S12PFG implements fully asynchronous dual-port architecture with separate address, control, and I/O buses per port-no shared bus arbitration logic. Each port features independent R/W, OE, and address decoding, enabling concurrent read/write operations without BUSY signal dependency.
It uses standard-power CMOS technology with TTL-compatible input thresholds (VIH = 2.2 V min, VIL = 0.8 V max) and delivers guaranteed 12 ns read cycle time (tRC) and address access time (tAA) under commercial conditions (0°C to +70°C) at VCC = 5.0 V ±10%.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Memory Organization | 4K × 9 bits (36 Kbit total, 9-bit wide data path supports parity) |
| Access Time (tAA) | 12 ns max - enables sub-83 MHz synchronous interface clocking |
| Read Cycle Time (tRC) | 12 ns max - defines minimum consecutive read interval per port |
| Supply Voltage | 4.5 V to 5.5 V - compatible with legacy 5 V TTL logic rails |
| Active Power (ICC) | 250 mA max at fMAX - translates to ~750 mW typical at 5 V |
| Operating Temperature | 0°C to +70°C - commercial-grade thermal envelope for non-industrial environments |
| I/O Capacitance | 10 pF (output), 9 pF (input) - ensures clean signal integrity up to 100 MHz edge rates |
Pinout & Package
Package: 64-pin thin quad flatpack (TQFP), body size 14 mm × 14 mm × 1.4 mm, lead-free (Pb-free) green finish.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| A0L–A11L | Left-port address inputs | 12-bit address bus for left-side memory access (4K = 2¹²) |
| A0R–A11R | Right-port address inputs | Independent 12-bit address bus for right-side access |
| I/O0L–I/O8L | Left-port bidirectional data | 9-bit data path supporting parity bit insertion or error checking |
| I/O0R–I/O8R | Right-port bidirectional data | Electrically isolated 9-bit data path; no contention with left port |
| R/WL, R/WR | Left/right write enable | Active-HIGH control: HIGH = read, LOW = write |
| OEL, OER | Left/right output enable | Active-LOW control: LOW enables outputs; HIGH places I/O in high-Z |
| VCC (pins 17, 33, 49) | Power supply | Three dedicated 5 V supply pins reduce IR drop and noise coupling |
| GND (pins 13, 27, 41, 63) | Ground reference | Four ground pins ensure stable return paths and minimize ground bounce |
Key Features
| Feature | Design Value |
|---|---|
| True dual-port memory cells | Enables simultaneous read from identical address on both ports without arbitration logic or latency penalty |
| 12 ns commercial access time | Supports real-time inter-processor handshaking in <12 ns latency-critical subsystems |
| 9-bit data width with parity option | Allows user-configurable 8+1 bit framing for error detection in serial data links or packet buffers |
| Fully asynchronous operation | Eliminates clock domain crossing issues; each port operates independently with no global clock required |
| TTL-compatible I/O | Direct interfacing with legacy 5 V microcontrollers, FPGAs, and ASICs without level-shifting |
Applications
| Telecom Packet Buffering | Real-Time Inter-Processor Communication |
|---|---|
Use Scenario: Storing and forwarding variable-length ATM or Ethernet frames between line-card and switch-fabric processors. IC Role / Device Role / Timing Role: Dual-port SRAM acting as zero-wait-state FIFO buffer with independent ingress/egress pointers. Use Value: Eliminates BUSY-wait cycles during concurrent frame write (from PHY) and read (to fabric), sustaining full wire-rate throughput. |
Use Scenario: Shared memory between two DSPs executing parallel signal processing tasks in radar or audio beamforming. IC Role / Device Role / Timing Role: Synchronization-free memory resource enabling lock-step or loosely coupled data exchange. Use Value: Enables deterministic <12 ns read-to-read latency across ports, critical for phase-aligned sample transfer. |
| Video Frame Storage | Industrial PLC Data Exchange |
Use Scenario: Holding one complete NTSC/PAL frame (720×480×2 bytes) in embedded vision systems with dual-camera input. IC Role / Device Role / Timing Role: Ping-pong frame buffer where one port writes incoming sensor data while the other reads processed output. Use Value: 12 ns tAA ensures pixel-clock-aligned capture without pipeline stalls; 9-bit width accommodates YUV 4:2:2 packing. |
Use Scenario: Exchanging status registers and control commands between main PLC CPU and motion-control co-processor. IC Role / Device Role / Timing Role: Deterministic shared memory node in deterministic industrial Ethernet protocols (e.g., EtherCAT slave side). Use Value: Asynchronous dual access guarantees sub-microsecond response to I/O update requests without software arbitration overhead. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar dual-port SRAM applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| CY7C024AV-12AXC | 4K × 16 organization, 12 ns speed, 3.3 V core (5 V tolerant I/O), different pinout | Higher data width but incompatible 16-bit interface; requires PCB redesign | Select only if 16-bit data path and 3.3 V system integration are required |
| AS7C34098B-12TIN | 4K × 9, 12 ns, 3.3 V supply only, no 5 V tolerance | Not interoperable with 5 V TTL logic; lacks VCC = 5 V ±10% compliance | Choose only for new 3.3 V designs where voltage translation is acceptable |
Compared with CY7C024AV-12AXC and AS7C34098B-12TIN, the IDT7014S12PFG uniquely retains native 5 V TTL compatibility, true 4K × 9 organization, and PLCC/TQFP package options-making it the only drop-in replacement for legacy 5 V dual-port memory systems requiring minimal layout change.

FAQ
What is the operating temperature range of the IDT7014S12PFG?
The IDT7014S12PFG is rated for commercial temperature operation from 0°C to +70°C. It does not support industrial-grade operation (−40°C to +85°C); that capability was discontinued per Renesas PDN# SP-17-02. The IDT7014S12PFG must be used within its specified ambient range to guarantee 12 ns access time and electrical specifications.
Does the IDT7014S12PFG support simultaneous write operations to the same memory location?
No-the IDT7014S12PFG has no on-chip arbitration circuitry. Simultaneous writes to the same address from left and right ports may result in partial or indeterminate data being stored. System-level arbitration (e.g., external logic or software protocol) is required to prevent conflicting writes. The IDT7014S12PFG datasheet explicitly warns against this condition.
What package type is used for the IDT7014S12PFG?
The IDT7014S12PFG uses a 64-pin thin quad flatpack (TQFP) with package code PNG64, body dimensions 14 mm × 14 mm × 1.4 mm, and lead-free (RoHS-compliant) green finish. It is distinct from the PLCC variant (PLG52) and requires matching footprint and reflow profile.
Can the IDT7014S12PFG operate with a 3.3 V supply?
No-the IDT7014S12PFG is specified only for 5 V ±10% (4.5 V to 5.5 V) operation. Its input thresholds (VIH = 2.2 V min), output drive strength, and internal logic are optimized for 5 V TTL compatibility. Using 3.3 V will violate DC operating conditions and cause functional failure. The IDT7014S12PFG is not 3.3 V tolerant.
How many VCC and GND pins does the IDT7014S12PFG have, and why?
The IDT7014S12PFG has three VCC pins (17, 33, 49) and four GND pins (13, 27, 41, 63) to minimize power distribution impedance and suppress switching noise. This multi-pin configuration reduces voltage droop during high-frequency I/O transitions and improves signal integrity-critical for maintaining 12 ns timing margins across all 18 data lines and dual address buses.
